Troubleshooting

Most difficulties in audio systems are the result of incorrect connections, or improper control settings. If you encounter problems, isolate the area of the difficulty, check the control settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the RA‑1520 refer to the suggestions for the following conditions:

Power Indicator Is Not Lit

The power indicator ring around the power button should be lit whenever the RA‑1520 is plugged into the wall power outlet and the POWER switch is pushed in. If it does not light, test the power outlet with another electrical device, such as a lamp. Be sure the power outlet being used is not controlled by a switch that has been turned off.

Fuse Replacement

If another electrical device works when plugged into the power outlet, but the power indicator still will not light when the RA‑1520 is plugged into the wall outlet, it indicates that the internal power fuse may have blown. If you believe this has happened, contact your authorized Rotel dealer to get the fuse replaced.

No Sound

Check the signal source to see if it is functioning properly. Make sure the cables from the signal source to the RA‑1520 inputs are connected properly. Be sure the LISTENING selector is set to the proper input. Be sure the SPEAKERS selector is set to the proper position. Check the wiring between the RA‑1520 and the speakers.

Protection Indicator Is Lit

The front panel indicator lights when the RA‑1520 protection circuits have shut off the amplifier. Typically, this occurs only when the ventilation openings are blocked, when there is faulty speaker wiring, or after a period of extreme use. Turn off the system and wait for the amp to cool. Then push the front panel power switch in and out to reset the protection devices. If the problem is not corrected or reoccurs, there is a problem with the system or the amplifier itself.

Remote Control Code Conflicts

Rotel uses the same IR remote control codes for all its audio products. In systems that have multiple Rotel products, the IR control codes of a remote control that is supplied with one product may interfer with the control codes of another product. The RR-AT94 and the RA-1520 can be set to alternate control codes to prevent such conflicts.

To change the IR codes of the RR-AT94, press the Phono button and the 2 button at the same time. To change the IR codes of the RA-1520, point the RR-AT94 at the RA-1520 then press and hold the 2 button for 5 seconds. The LED in the volume control will flash to indicate the IR code has changed.

Note: After changing the remote codes for the remote control and the preamplifier as described above, the remote control will no longer operate the Rotel tuners. To return the RR-AT94 IR code to the default setting, press the Phono button and the 1 button at the same time. To return the IR code of the RA-1520 to the default setting, point the RR‑AT94 at the RA-1520 and press and hold the 1 button for 5 seconds. The LED in the volume control will flash to indicate the IR code has changed.

Resetting the IR code

Should you need to reset the IR code, press the MUTE button A on the RR-AT94 remote control for more than 5 seconds while pointing it at the RA-1520. The unit will return to default condition and the Listening CD LED q will turn on to indicate the IR code is reset. Contact your authorized Rotel dealer for further information.
